  • @alain.takoudjou : is it me or does this script always run 4 times, even if first call to applyEditChage (instance.applyConfigChanges() nowadays) is succesfull ?

    This behavior is the same currently : https://lab.nexedi.com/nexedi/slapos.toolbox/blob/1c8269b2b12414846dab010abbc289a99f1faf1d/slapos/monitor/monitor_config_write.py#L184

  • @Nicolas here, applyEditChage method will check if there is some configuration changes to apply. if yes it apply, else will just return. It checks 4 times because this script is run by cron (every minutes). So run 4 times help to apply a changes faster and not wait 1 minute in monitor interface to see if have a configuration applied.

  • Ho right ! I already heard about it. Sorry for asking you again --'
